If you didn't manually preheat the bed and hotend Matter Control will, when you press print, first heat the bed and then after it gets to temp will heat the head.
Although I have had 2 or three cases where it had just started to print something and I look over and see no flow (after a couple layers) and then notice that the head heat is off [ and maybe bed heat too] It had started fine but turned the heat off. I think I had that happen near the end of a print, too. In one case I hit the pause, hit the preheat buttons again, hit resume, and when it got hot it continued where it left off and the print turned out fine.
I also sometimes see Matter control telling me my model has many times the number of layers that it actually has (in the thousands), and if you step through the layers with the built-in viewer thing you can see that it is counting the peremeter as layer 1, the left foot as layer 2, the right foot as layer 3, and so on. like the layer number goes up by one after every retract operation.
It still prints fine. I can't remember if that is CURA or matterslice that does that, but I think it is only the one slicer.

Refused to heat up the hotend. Probably fixable by changing the "start gcode" but IMO slic3r is not worth the hassle, so I never bothered.
Cura doesn't have a triangle infill option last I checked. That's one reason I like MatterSlice. Triangles ftw.
I've also seen the same thing regarding the "thousands of layers." I don't know why it does that but it doesn't seem to affect the print, so for now I'd write it off as a cosmetic bug that will probably get fixed sooner or later; after all, all this software is still under active development.
I've never had MatterSlice get hung up on a model though, do you want to post the model here so we can see if other people have the same issue with it?
